Yes, it's normal to see dead worms coming out in her poop a few days after being dewormed - this means that the medication is working. As long as she is acting normal otherwise, this shouldn't be any cause for concern :)

    If it was a worm in her stool, this would only be related to the dewormer. I would say it is not unusual to see worms passing out for up to one week after getting the medication. If you can, collect the sample in a bag and see if you were that veterinarian or someone at the office can take a look at it and confirm. If it is still the worm, they will likely recommend some additional dewormings. The diarrhea generally will respond within 24 to 48 hours after starting the medication. So the fact that the stool is still loose it’s not unusual. I hope this is helpful and please feel free to post any additional questions.

    Yes, this is normal. It means the deworming treatment is working to kill all the worms in Bailey's GI tract. Even though she never had worms in her poop before doesn't mean that she didn't have, and you are seeing she clearly had them. Oftentimes, a fecal exam with a microscope is needed to see the eggs of the worms to confirm a puppy has them. Best of luck, I hope this helps!
